Headworn Microphone
The Shure Beta Microphone Series BETA 54 is a subminiature, electret condenser headworn microphone. It provides uncompromised sound quality and reliability with minimal visibility in applications such as broadcast, theater, and touring. Despite the small size, the condenser element delivers full, clear, and natural reproduction of speech and vocals.

The microphone features a durable, low-profile wire frame headband which is fully adjustable for stability and comfort. A plastic carrying case protects the microphone and its accessories.

The BETA54 now features improved RF immunity against cellular and RF devices.

A wireless version is available as the WBH54.
